For Liam, finding out his sister Samantha did porn didn't come as a surprise. For her eighteenth birthday her then boyfriend -- a 32-year-old photographer -- had given her a brand new set of tits, increasing her bosom to an impressive 34DD. Sam had been delighted with them, and was probably even more delighted with her parents' horror at their little girls new look. She had goaded them at every opportunity, walking around in nothing but a bikini top as soon as the sun peaked out from behind a cloud. It was only the threat of being kicked out that eventually forced Sam to calm down, although only slightly. The photographer hadn't lasted long, and only got to play with his new toys for six months before Sam dumped him to, in her own words; "have more fun." Fun certainly wasn't hard to come by for Sam - her new tits, year-round tan, long blonde hair and tight, toned body meant that every guy she met wanted to have their way with her -- and Sam absolutely loved it.

So, for Liam, when he got a text from a friend containing the URL to a website for a pornstar called Sammy Love, and the words 'isn't that ur sister?' it didn't shock him that much when he logged onto the site and was greeted by his 19-year-old little sister's smiling face and naked breasts. Truth be told, it had turned him on. He'd come to terms with the fact that he found his sister attractive the day she'd come home with her new breasts, and had often spied on her when she was in the shower of having one of her many lingerie parties with her friends. Little sister Sam - or Sammy Love -- was a hot girl who just happened to be his sister.

Confronting Sam about her secret was easy; in fact Liam revelled in it. He wasn't coy or tacit about it, instead choosing simply to greet her as Sammy Love when she arrived home one afternoon. It was the first time in his 18 years of being her sister that he saw genuine fear in Sam's eyes.

"How did you find out?" she asked, shocked, after wiping tears from her cheeks and eyes.

"I found your website. Why Sammy Love?" he had asked, with a grin on his face. Sam didn't answer.

"Are you gonna tell Mum and Dad?"

"No."

He meant it. He wasn't going to blackmail her or hold the sword of Damocles above heard, what Sam did with her life was her business and Liam knew he had no place interfering with it. That being said, for the last sixth months it hadn't stopped him from teasing his sister about her choice of 'career', and he would often ask her distasteful or unpleasant questions when she arrived home. His favourite at the moment was "did you drink much today?" which he would make sure to ask when at least one of their parents was present. They thought he was referring to Sam's partying, but if they'd have paid attention to their daughter's reaction they'd have probably realised that there was a little more to it than that.

Liam knew he would be in no place to tease Sam if she ever found out his 'little secret', however. A quick check of his internet history would expose him, which was why he'd started locking his bedroom door every time he left the room. His parents thought he was up to something, but the 'something' he was actually up to was way beyond anything they could imagine. He couldn't become a member of Sammy Love's website; that much was obvious. He doubted whether she actually had anything to do with the running of the site herself, but if someone saw his surname on the membership list then there was a chance that two and two would be put together.

God bless video streaming sites, then. Liam had built up quite a collection of Sammy's videos; all of them were catalogued in his favourites to be watched over and over again. She had never done anything that Liam would consider truly 'hardcore', mostly sticking to lesbian or standard 'boy fucks girl' stuff. There was one video of some nameless guy shooting his load all over his little sisters tits, which was a video Liam liked to cum to. He imagined that it was stream after stream of his own cum splashing down onto her breasts, and that she was looking into his eyes as she massaged the hot, milky liquid into her skin.

Inevitably, the post-wank shame hit him and he would close down all his browser windows, clean himself up and then spend half an hour feeling guilty about what he'd done. Then he'd start feeling horny again and images of Sam would fill his mind.

Aside from the easy access to images of her getting fucked, Sam's career in porn had other upsides. The fact that all her female friends now seemed to be unutterably gorgeous was the main one, they were all in porn as well, and they would all come over to the house at least once a week. Right now was one of those times, and Liam sat in the living room watching four hot women, one of them his sister, through the French doors from his living room as they sat in the garden chatting whilst wearing nothing but tiny bikinis. He knew all their names -- Sam, obviously, as well as Belinda, Carly and Lori - or, if you wanted to search for them on the internet; Cassie Hart, Violet Ray and Andi Rhodes.

His sister was the stereotypical blonde porn star. Belinda was redheaded, light skinned, small breasted and only just 5'2". Liam thought she'd get sunburnt given her light, almost porcelain skin, although much to his delight Sam had started helping her out by rubbing lotion on every visible inch of flesh. Carly was a brunette, with hair that reached halfway down her back and sometimes covered her pert 32C breasts. She was somehow ignoring the action between Sam and Belinda as she chatted away with Lori, another brunette, with slightly smaller breasts and a short, almost boyish haircut.

Liam could feel his engorged cock pressing against his boxers. He'd been hard almost from the moment he came into the lounge and saw the girls outside, giggling and frolicking in the South England sun. Now, though, he was fully erect, and knew he'd have to go and relieve himself. Luckily his parents were out and the girls didn't look like they'd be coming in any time soon, so he was able to take himself up to his room without the danger of anybody noticing his funny walk.

Liam removed his t-shirt as he entered his room - he liked to be completely naked when he masturbated so his shorts, boxers and socks soon found themselves piled on top of the discarded black shirt. The bedroom door slammed shut and Liam threw himself onto his bed, cursing the location of his house -- he couldn't watch the girls out of the window as he stroked himself, as the houses that backed onto his would have a clear view of what he was doing, should any one of his neighbours happen to pass by their windows. Closing his eyes Liam gripped his thick shaft, and the voice that had been telling him he'd forgot to lock his door was soon banished and replaced by the sound of his sister moaning and squealing in one of her videos.

Knowing the object of his desires was downstairs wearing practically nothing had sent Liam's head swimming. He struggled to maintain concentration as his right hand pumped up and down on his 7 inch dick, as he tried to visualise his sister straddling him and riding him like she'd ridden so many other men.

Liam's concentration coupled with forgetting to lock his door would come back to haunt him, though. He didn't hear Belinda and Carly enter the house, yelling to Sam and Lori they'd "be out in a second." He didn't hear them climb the stairs, as their bare feet barely made a sound on the carpeted floor. He even missed Carly whispering to her red-headed friend; "have you ever wondered what Sam's brothers' room looks like?" followed by the two girls' giggles.

Opening the door, Belinda almost did a double take as her eyes took in the fantastic site before her. She had always thought Liam was attractive, but never imagined he'd be so well endowed. She was no stranger to big cocks, but seeing one so big in her private life was unusual, to say the least. She felt Carly squeeze her head past hers to get a look, before her brunette friend dragged her back into the hallway.

"We've got to go and get Sam!" exclaimed Carly, barely able to conceal her excitement.

"Carl, no, we can't!" said Belinda, only just managing to stop herself from laughing.

"Oh come on, she'll think it's fucking hilarious!"

Carly grabbed Belinda by the arm and the two made sure to make no noise as they hurried down the stairs, before sprinting out into the back garden. Sam and Lori looked up from their conversation at the two slightly out of breath girls stood in front of them.

"What have you two been up to, then?" Lori asked, suggestively.

"Sammy, you've got to come with us." Carly ignored Lori, and dragged Sam to her feet.

"Oh, come on, can't it wait?" Sam protested, but she couldn't outmuscle Belinda or Carly, and they were soon joined by Lori whose interest had been piqued.

Liam was now completely lost in his Sammy fantasy. His hand had been replaced by her shaven, smooth pussy, which he was fucking furiously from behind as she called out his name. Her hands grabbed the back of his head and pulled him into her, and she mashed her lips against his and darted her tongue into his mouth. Liam was ready to cum, he could feel his hips bucking and thrashing, but suddenly he was stopped in his tracks.

"Oh dear, Liam... what are you doing?"

The sarcasm in Sam's voice pierced through his fantasy, and his eyes shot open as he jerked up violently. Sam, backed up by Belinda, Carly and Lori, was standing just inside his doorway. He tried to speak but his throat was bone dry, and he could feel his cheeks burning up as the four girls stared a hole in him; all with grins on their faces -- except for Sam. His sister looked like the cat that got the cream, as if she'd finally 'won' one over her brother. The other girls followed as she walked over to his bed and took a seat, and soon he was surrounded by the four porn stars. He felt self conscious and penned in, and jumped when Carly's hand came to rest on his lower leg.

"So, what were you thinking of?" Sam asked, putting on her best 'innocent' voice whilst staring into Liam's eyes. He looked away, only to find three other pairs of eyes looking at him.

"I think he's a bit shy!" Belinda said, breaking into a giggle.

"I don't know why, he's impressive."

"Oh my god, Lori!" Sam cried, having been taken aback by her friend's forthright views on her brother's manhood. Despite the embarrassing situation Liam still felt his ego swell slightly when Lori complemented the size of his cock, he knew he was big but to have a porn star say it simply drove it home. The four girls started laughing again, and now Carly was crawling up next to him.

"So, Liam. Were you thinking about us? It's alright, you can be honest." She grinned seductively at him, running a hand up his toned stomach and then back down towards where the girls were sitting, although she stopped short of his still erect penis.

"I bet he was," Sam piped up, "that's why he was sitting in the living room for so long!"

More giggles, and Liam felt yet more embarrassment at just how close in their guesses they were.

"Ok, ok..." Belinda silenced the girls, "you don't have to tell us who you were thinking about. But now we're all sat here, who do you think is the most attractive?"

Instinctively, Liam's eyes shot to his sister -- and the game was up. She suddenly turned away, the look on his face when he glanced in her direction had been obvious, and Liam had barely managed an 'umm' before Carly squealed out his secret for the whole world to hear.

"No fucking way!" she cried, turning to the rest of the girls. "He likes Sammy!"

They laughed through shock more than anything else. Before he could even think to deny it Sam was on her feet and running for the door, her three friends following behind calling her name in mock concern. They shut the door behind them, and Liam was left on his own. He looked down at his impressive cock; it was still standing to attention, ready to be taken care of... and he couldn't help himself, as he once again gripped his long, hard member and began to stroke up and down, furiously and without any care of being caught again. He still thought of his sister, and the look on her face when she'd finally realised his feelings for her went beyond the normal brother-sister relationship. Cum erupted from the tip of his cock, shooting harder and further than it ever had before. It splashed on his chest, stomach and the bed sheets, and when he was finally empty he slowly got to his feet and began to clean himself up. This time, though, he felt no guilt about what he had been fantasising about. It was out in the open now.

Sam had made her friends leave almost as soon as they had followed her out of her brothers' bedroom. They had laughed and mocked her as they left, with Lori shouting back warning her not to "do anything... or anyone stupid!" She hated them for what they'd just done. Seeing her brother masturbating was funny, sure, but the little look he'd given her when Belinda had asked him who he thought was the best looking had turned her world upside down. What was she supposed to do? Her brother had basically just admitted to fancying her, how could she live with him and act as if everything was normal? Could she move out? No, she was making good money in porn but wanted enough money to be able to buy a house. Moving out and renting might mean never getting enough money for that, and she couldn't keep doing it for much longer than another year or so. She had already been in the industry longer than she'd already planned. Curled up in the foetal position on top of her bed covers, she drifted off to sleep and asked herself why her brother couldn't be normal.

Liam sat at the dinner table, flicking his cereal with his spoon. It was one in the afternoon, the house was empty, his parents were at work again and his sister hadn't been around since what he had termed 'the incident' occurred two days ago. Pushing his bowl away he stood up and stretched, when the sound of keys jangling diverted his eyes towards the front door. It swung open and in stepped Sam, dressed in tight pink jogging bottoms and a white hoodie.

"Hey," he said, but she ignored him. "Look, Sam, about the other day..."

"No, we're not -- and don't call me fucking Sammy. If I ever want to talk to you then it definitely won't be about THAT. It's sick, Liam, my friends might have laughed but you're disgusting."

Liam knew his feelings for his sister were wrong but there was no way he was going to take being spoken to like that. As he stepped round the table and stood in front of his sister, his tone became much sterner.

"I'm sick? What about you!? Most other sisters would have seen their brother wanking and left, you came and sat on my bed! If I'm sick then you're just as bad as me."

Liam could see tears welling up in Sam's eyes as she looked up at him. His aggression had clearly taken her by surprise, and she knew she couldn't answer that.

"Ok, so we're both sick -- at least I don't want to fucking talk about it! Listen to me, Liam; YOU. FANCY. YOUR. SISTER." She spelled it out for him. "Doesn't that sound just a little bit fucked up, even in your head?"

Suddenly, Liam found himself desperately trying to think of a way to defend himself, and although he knew that what he had come up with was weak he said it anyway.

"I never said I fancied you, I never said anything. I just thought you were the most attractive."

Sam squeezed past him and made for the stairs, but Liam caught up with her and grabbed her by the arm.

"If you tell anyone I'll tell Mum and Dad about what you do for a living."

Sam, now on the first step on the stairs, spun round. Now she was looking down on him, an irony not lost on either of them.

"You know what? Go ahead. I'm sure they'll be pissed but wait until they hear about you! Their sick little son; I bet if I looked on your computer now I'd find a load of videos of me, wouldn't I?"

The look on Liam's face gave Sam her answer, and she cackled almost maniacally. As Liam tried to regain his composure Sam turned and ran up the stairs taking two steps at a time, and made a beeline for his room. Liam caught up with her just as she stepped through the door he once again had forgot to lock, and placed herself in front of his laptop. Before she could see anything Liam wrapped his arms around her waist from behind and spun her into the middle of the room. He felt a kick hit him in the thigh, and then Sam's arms caught him on either side of the face.

"Get off me you sick cunt!" Sam screamed as he released her, unceremoniously dumping her on the floor. Now his little sister was in full on vindictive mode, laughing at his desperation. She got to her feet and pushed him, slapping her hands hard against his chest, and swung a leg at him. Liam's reflexes kicked in and he grabbed her foot, before tucking it under his left arm. His right hand reached out and grabbed her by the throat, and he charged forward causing her to hop backwards towards his bed. She collapsed down on her back and Liam fell on top of her, before readjusting his position so he was straddling her just over the stomach. Sam tried to free herself but Liam was too strong, grabbing her wrists and pinning her hands against the bed just above her head.

Sam stopped struggling and Liam loosened his grip slightly, but not enough to let her loose. Both breathed heavily and locked eyes with each other, when Liam suddenly felt the blood rushing to his cock. Sam noticed immediately, as his erection grew and grew until it was clearly visible through the material of his shorts, and poking into her stomach.

"You just can't help yourself, can you?" She had stopped wriggling completely now, and had caught her breath. "So, big brother, you've finally got me on your bed. What are you going to do?"

She continued to stare at him, watching him weigh up his options. If he let her go, she had won. But what else could he do?

"Come on, Liam. You know what you want to do now. Do it, you sick fuck."

Whatever he did, Liam realised; Sam had won either way. Slowly he lowered his head towards hers, opening his mouth slightly. She didn't try to avoid him, and instead kept her eyes focused on his as he pressed his lips to hers. Sam didn't react so he kissed her more forcefully, pushing the back of her head down into the mattress of the bed. As he felt her mouth open slightly he slipped his tongue inside her mouth, she accepted it and greeted it with hers. Somewhat reluctantly he opened his eyes expecting to see hers, but they were closed. Did she want this? There was only one way to find out, and he let go of her wrists. They remained in place for a moment, before wrapping themselves around him and Sam locked her hands tight against his back. He tried to pull his head away, but she held it in place and continued to kiss him.

Liam rocked his hips so his cock grinded against her, and they both manoeuvred so his cock was pushing into her mound. Finally Sam broke the kiss and pushed Liam back, sat up ripped her top off. She had been wearing nothing underneath, and her big, round, perfect breasts were now within his reach. Her pink nipples were erect and pointing towards him, she jiggled her chest slightly and looked across at him.

"Suck on my tits, big brother," Sam demanded, and Liam didn't need to be told twice. He practically dived forward and took her right nipple into his mouth, sucking it first before biting it gently with his teeth. He pawed at the other with his right hand, and felt his sisters' hands gently caressing his back.
